完整性约束违规：1048列“名称”不能为空

Question

I'm making a REST API to register a user using PHP and Slim framework. It's giving me an error when I run it in advanced REST client:

{"error":{"text":SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null}}

The code for the register module is as follows:

function insertUpdate() {
    $request = \Slim\Slim::getInstance()->request();
    $update = json_decode($request->getBody());
    $sql = "INSERT INTO users (name,email,password,phoneNumber,imageUrl,created_at) VALUES (:name, :email, :password, :phoneNumber, :imageUrl, :created_at)";
    try {
        $db = getDB();
        $stmt = $db->prepare($sql);  
        $stmt->bindParam("name", $update->name);
        $stmt->bindParam("email", $update->email);
        $stmt->bindParam("password",$update->password);
        $stmt->bindParam("phoneNumber",$update->phoneNumber);
        $stmt->bindParam("imageUrl",$update->imageUrl);
        $time=time();
        $stmt->bindParam("created_at", $time);

        $stmt->execute();
        echo "Register successfull";
    } catch(PDOException $e) {
        //error_log($e->getMessage(), 3, '/var/tmp/php.log');
        echo '{"error":{"text":'. $e->getMessage() .'}}'; 
    }
}

Stack Trace:

function insertUpdate() {
        $request = \Slim\Slim::getInstance()->request();
        parse_str($request->getBody(),$update); 
        $sql = "INSERT INTO users (name,email,password,phoneNumber,imageUrl,created_at) VALUES (:name, :email, :password, :phoneNumber, :imageUrl, :created_at)";
        try {
            //Validate your filed before insert in db
            if(!is_array($update) || (!$update)) {
                throw new Exception('Invalid data received');   
            }
            // put your require filed list here
            if((!$update['name']) || (!$update['email']) || (!$update['password'])){
                throw new Exception('Missing values for require fields');
            }
            $db = getDB();
            $stmt = $db->prepare($sql);  
            $stmt->bindParam("name", $update['name']);
            $stmt->bindParam("email", $update['email']);
            $stmt->bindParam("password",$update['password']);
            $stmt->bindParam("phoneNumber",$update['phoneNumber']);
            $stmt->bindParam("imageUrl",$update['imageUrl']);
            $time=time();
            $stmt->bindParam("created_at", $time);

            $stmt->execute();
            echo "Register successfull";
        } catch(PDOException $e) {
            //error_log($e->getMessage(), 3, '/var/tmp/php.log');
            echo '{"error":{"text":'. $e->getMessage() .'}}'; 
        }catch(Exception $e) {
            //error_log($e->getMessage(), 3, '/var/tmp/php.log');
            echo '{"error":{"text":'. $e->getMessage() .'}}'; 
        }
    }
